چکیده
This papa presaits some advances on the development of pembation methods for the annlysis of inter-area oscillations in complex power systems. A nonlinear model of the power system that includes the representation of second-order effects is proposed. Based on this representntion, the normal forms of vector fields are used to analyse non-linear modal inkraction under stressed operating conditions. The p r d u r e s developed are tested on a practica1 46-machine, 191-bus test system.

Coordinated Control of Doubley Fed Induction Generator Virtual Inertia and Power System Oscillation Damping Using Fuzzy Logic
Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...
متن کاملDesign Supplementary Controller Based on Stabilizing Effect of Delay for Damping Inter Area Oscillations in a Power System
The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...

Unlike the existing views that was introduced the existence of delay caused by the transmission of wide area measurement system data (WAMS) into the controllers input of the power oscilation damping (POD) by communication networks as a reason for poor performance of the POD controllers. This paper shows that the presence of time delay in the feedback loop may improve the performance of a POD co...
